When a Xiaomi smartphone suddenly stops giving away the Internet, often catches the user by surprise, especially if mobile traffic is urgently needed on a laptop or tablet.The problem can be in both a banal software failure and incorrect operator settings that block the modem function. Owners of devices with a MIUI shell or a new HyperOS regularly face this, and the standard slider switching in the notification curtain ceases to help.
Before you panic and bring your gadget to the service, you need to do a deep diagnostic of system parameters, often because of frequency conflict or the exhaustion of the limit of connected devices, which the system does not say, we will analyze all possible scenarios, from simple reboots to editing hidden APN configuration files, so you can restore the stable operation of the network.
Basic diagnostics and simple solutions
The first thing to do is to eliminate the basic failures that accumulate during the long run of the operating system. RAM can be overflowing with background processes that block network services. Try to perform a complete reboot of the device, rather than just turn off the screen. This will clear the cache of network modules and force the smartphone to reconnect to the operator's towers.
Make sure you're on balance. SIM-The card does have funds and a tariff plan is activated to distribute the Internet. Some operators require a separate subscription or block modem modem at certain rates. USSD-team to exclude financial blocking of the service.

Try to turn on the air mode on 10-15 It'll force the device to re-register on the network and often solve the problem of the hanging. IP-address.
If the basic methods didnโt work, check if the limit on the number of connected customers is activated. Xiaomiโs default access point settings may have a limit that has already been exhausted, even if you donโt see anyone visually on the list.
Access point settings and frequency ranges
One of the most common reasons why the hotspot on Xiaomi is not turned on is the frequency band conflict: Modern smartphones try to operate in the 5 GHz band for maximum speed, but older laptops or tablets may simply not see this network.
To do this, go to Settings โ Connection and Sharing โ Wi-Fi Access Point. Click on your network name or select โSetting up the hotspot.โ Find the โRangeโ section and change the value from 5 GHz to 2.4 GHz. This action will greatly improve compatibility with external devices.
โ๏ธ Checking frequency settings
Also worth paying attention to is the type of encryption: If you set the value "Not secure" or outdated WEP protocol, some modern devices may refuse to connect or your smartphone will block the start of the distribution. Set the WPA2 PSK standard, which is the gold standard for security and compatibility.
In some cases, changing the broadcast channel helps: If the air is clogged with neighboring routers, your Xiaomi may not be able to take up the free frequency. Try manually setting a specific channel (for example, 1, 6 or 11) instead of automatically selecting to avoid collisions.
Problems with APN and operator settings
A critical element for mobile internet and distribution is the APN settings. If this section has incorrect data or a software failure, the phone will have a signal but cannot transmit data. Operators often update their gateways, and the old settings may stop working.
To fix this, go to Settings. โ SIM-maps and mobile networks โ Choose yours. SIM โ Access points (APN). In the upper right corner, click the menu button (three dots) and select Reset settings. This will return the original settings prescribed by the operator.
Hidden APN settings
If automatic reset didnโt work, create a new access point manually, enter the name (any), APN (address that can be found on the operatorโs website, for example, Internet.mts.ru or Internet.beeline.ru) and save the profile by ticking it.
โ ๏ธ Attention: After changing the settings APN Make sure to turn on and off Flight mode to make the changes effective. Without rebooting the network module, the phone can continue to use old, non-working settings.
Restrictions by the communications operator
Do not forget that many mobile operators implement Internet distribution detection systems (TTL-If your plan does not provide free traffic, the operator can block the connection or reduce the speed to zero, in which case the access point on Xiaomi is formally turned on, but the Internet on the connected devices does not work.
Check your tariff terms in the carrier app. Often there's a "Unlimited Handout" option or gigabyte-specific packages for the modem. If you've reached the limit, the network will only work on the smartphone itself.
It is believed that changing the IMEI or using special applications helps to bypass these restrictions, but such actions can lead to the locking of the device by the operator or violation of warranty conditions.
Network reset and software conflicts
If a software failure is deeper than just an APN setting, it will require a complete reset of network settings, which will remove all stored Wi-Fi passwords, Bluetooth pairs, and mobile network settings, returning them to factory status, often solving the problem of the system forgetting how to properly initiate a connection.
Reset via Settings โ Connection & Sharing โ Reset Wi-Fi, Mobile Networks and Bluetooth. Confirm and wait for the modules to reboot. After that, re-enter the Wi-Fi password (if necessary) and try to start the hotspot.
Third-party applications, especially antivirus or Internet accelerators, can also be at odds, and try running your smartphone in Safe Mode (usually by pressing the off button on the lock screen) and checking the hotspot. If it's safe, one of the apps installed is to blame.
| Action. | Impact on data | Efficiency |
|---|---|---|
| Reboot. | Data is retained | Low (temporary disruption) |
| APN reset | Data is retained | Medium (setting errors) |
| Resetting the network | Wi-Fi passwords are being removed | High (deep errors) |
| Reset to factory | All data is deleted | Maximum (critical failures) |
Hardware problems and overheating
In rare cases, the problem is physical: the Wi-Fi module in Xiaomi smartphones when the Internet is actively distributed, experiences a high load. If the device body is very hot, a protection system is triggered that forcibly disables the access point to avoid damage to the radio module.
Try removing the case if it's dense and impairing heat transfer. Put the phone on a cold surface (not on the battery!) during the handout. If the problem only occurs when the heat is heated, it's a clear sign of overheating.

If the hotspot goes off immediately after switching on and the phone is hot, let the device cool down, and if you continue to use it, you can crash the Wi-Fi chip.
It's also worth checking the antenna module, and if the phone crashes, the antenna's contact with the board may be disrupted, in which case the signal may be weak, and if you try to distribute, the device will lose the network, which requires intervention in the service center.
